Product details
Overview
TPS54060DRCT from Texas Instruments is a 60-V, 0.5-A synchronous step-down DC-DC converter with integrated 200-mΩ high-side MOSFET, Eco-Mode™ pulse-skipping operation, 116-μA no-load quiescent current, and adjustable 100-kHz to 2.5-MHz switching frequency - used in industrial power rails for 12-V/24-V/48-V systems requiring wide-input, low-quiescent-current regulation.
For engineers reviewing the TPS54060DRCT datasheet, TPS54060DRCT pinout, TPS54060DRCT application, or TPS54060DRCT equivalent, key selection considerations include input voltage range (3.5–60 V), light-load efficiency via Eco-Mode™, PWRGD power-good monitoring, adjustable UVLO using EN pin, and thermal performance in the 3-mm × 3-mm VSON package.
Technical Context
The TPS54060DRCT implements constant-frequency peak current-mode control with internal slope compensation to prevent subharmonic oscillation across duty cycles. Its error amplifier drives COMP to regulate output via external VSENSE feedback resistors referenced to a 0.8-V internal reference.
It features dual-mode RT/CLK pin operation: resistor-set frequency tuning (100–2500 kHz) or external clock synchronization with PLL lock-in (<100 μs). The BOOT-PH UVLO (2.1 V threshold) enables high-duty-cycle dropout operation while maintaining gate drive integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 3.5 V to 60 V - supports direct connection to unregulated industrial bus rails including 12 V, 24 V, and 48 V nominal systems. |
| Output Current | 0.5 A continuous - delivers regulated power to microcontrollers, sensors, and interface ICs without external current boosting. |
| Quiescent Current | 116 μA at no load - enables battery-backed or energy-harvesting applications with multi-year standby life. |
| Switching Frequency | 100 kHz to 2.5 MHz - allows optimization of inductor size and efficiency; set via RT resistor or synchronized to external clock. |
| Internal Reference | 0.8 V ±1.2% - sets precise output voltage via external resistor divider; stable over –40°C to +150°C junction temperature. |
| Power-Good Threshold | 94% to 107% of nominal VOUT - open-drain PWRGD asserts low outside this window, enabling system-level fault detection and sequencing. |
| Thermal Resistance (RθJA) | 40 °C/W (VSON package, custom board) - enables 0.5-A operation up to +125°C ambient with minimal heatsinking. |
Pinout & Package
TPS54060DRCT is housed in a thermally enhanced 3-mm × 3-mm, 10-pin VSON (DRC) package with exposed thermal pad (Pin 11) that must be soldered to PCB ground for proper thermal and electrical performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| PH (Pin 10) | High-side MOSFET source | Switch node connecting to inductor; requires low-inductance layout to minimize EMI and ringing during transitions. |
| BOOT (Pin 1) | Bootstrap capacitor connection | Supplies gate drive voltage to high-side MOSFET; requires 0.1-μF X7R/X5R ceramic capacitor between BOOT and PH. |
| VIN (Pin 2) | Main input supply | Accepts 3.5–60 V; includes internal 2.5-V UVLO with adjustable threshold via EN pin resistor divider. |
| GND (Pin 9) | Power and signal ground | Reference for all analog circuitry; must be connected to thermal pad (Pin 11) and low-impedance PCB ground plane. |
| VSENSE (Pin 7) | Error amplifier inverting input | Monitors output voltage via resistor divider; regulates output to 0.8 V reference with ±1.2% accuracy. |
| COMP (Pin 8) | Error amplifier output | Drives current-mode PWM comparator; connects to Type II/III compensation network for loop stability. |
| EN (Pin 3) | Enable / UVLO control | Pull below 1.2 V to disable; internal pull-up enables default operation; used to adjust UVLO threshold with external resistors. |
| SS/TR (Pin 4) | Slow-start / tracking input | Controls output ramp time via external capacitor; supports power sequencing by overriding internal reference voltage. |
| PWRGD (Pin 6) | Open-drain power-good output | Asserts low when VSENSE falls below 94% or rises above 107% of target - requires external pull-up resistor. |
| RT/CLK (Pin 5) | Frequency setting / sync input | Resistor-to-ground sets switching frequency; pulled above PLL threshold to accept external clock edges (300–2200 kHz). |
Key Features
| Feature | Design Value |
|---|---|
| Eco-Mode™ Pulse Skipping | Reduces switching losses at light loads, achieving >85% efficiency at 10-mA output while drawing only 116-μA input current. |
| Integrated High-Side MOSFET | 200-mΩ RDS(on) at 12 V BOOT-PH enables compact 0.5-A buck design without external switch or driver components. |
| Adjustable UVLO with Hysteresis | EN pin allows user-defined input undervoltage lockout threshold and hysteresis using two external resistors - critical for brown-out immunity. |
| Power-Good Monitoring | PWRGD provides system-level fault signaling for under-voltage (92%), over-voltage (109%), thermal shutdown, or EN-induced disable. |
| Thermal Protection | Internal thermal shutdown activates at 182°C junction temperature and automatically recovers after cooldown - prevents permanent damage. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM5164DRCT | 42-V max input, 0.6-A output, 3.5-μA shutdown current, no Eco-Mode™ - uses constant-on-time control instead of current mode. | Better suited for ultra-low-IQ always-on applications but lacks PWRGD and adjustable UVLO hysteresis. | Select LM5164DRCT when <1-μA shutdown current is mandatory and input never exceeds 42 V; retain TPS54060DRCT for 60-V robustness and precision power-good signaling. |
| TPS54260DRCT | Same family, 2.5-A output, identical pinout and feature set - differs only in current rating and RDS(on) (110 mΩ vs 200 mΩ). | Direct upgrade path for higher-current designs; shares same layout, compensation, and sequencing behavior. | Choose TPS54260DRCT if future-proofing for >0.5-A loads is required; otherwise TPS54060DRCT minimizes BOM cost and thermal footprint. |
Compared with LM5164DRCT, TPS54060DRCT offers superior input voltage range and integrated power-good signaling; compared with TPS54260DRCT, it trades current capability for lower cost and reduced thermal demand in space-constrained 0.5-A applications.

FAQ
What is the maximum input voltage rating for the TPS54060DRCT?
TPS54060DRCT supports an absolute maximum input voltage of 65 V, with recommended operating range from 3.5 V to 60 V. This makes it suitable for 48-V industrial buses and automotive systems subject to load-dump transients. Operation above 60 V is not advised for sustained use due to increased stress on the internal 200-mΩ MOSFET and boot circuitry.
How does Eco-Mode™ improve light-load efficiency in the TPS54060DRCT?
TPS54060DRCT enters Eco-Mode™ when output load drops below ~20 mA (dependent on inductor value), skipping switching pulses while maintaining regulation. This reduces gate drive and switching losses, lowering no-load quiescent current to 116 μA - significantly extending battery life in always-on sensor nodes and backup systems.
Can the TPS54060DRCT synchronize to an external clock, and how is it configured?
Yes, TPS54060DRCT synchronizes to an external clock via the RT/CLK pin. When pulled above the internal PLL upper threshold (~1.25 V), the pin switches from resistor-set mode to high-impedance clock input. Supported clock range is 300–2200 kHz, with PLL lock-in time under 100 μs - enabling noise-sensitive applications to align switching with system timing domains.
What is the role of the SS/TR pin in the TPS54060DRCT, and how is it used for power sequencing?
The SS/TR pin in TPS54060DRCT controls output voltage ramp rate via an external capacitor and supports tracking by accepting a voltage reference from another regulator. During startup, it overrides the internal 0.8-V reference, allowing precise sequencing of multiple rails - e.g., ensuring 3.3-V logic powers before 1.2-V core in FPGA systems - preventing latch-up or inrush faults.
Does the TPS54060DRCT require an external bootstrap diode, and what capacitor value is recommended?
No, TPS54060DRCT integrates the boot recharge diode, eliminating the need for an external component. A 0.1-μF X7R or X5R ceramic capacitor rated ≥10 V must be placed between BOOT and PH pins. This capacitor supplies gate drive voltage to the high-side MOSFET and is refreshed during low-side conduction - critical for stable 100% duty cycle operation near dropout.
